KAPA diameter of the pipe increases The maximum allowable pressure goes

Down

1

Most conservative KAPA formula is

B 31G

2

Most conservative to most liberal formula for K APA

B 31G; modified B 31G; effective area method

3

Define MOP

Maximum operating pressure as specified by the manufacture of the pipe

4

Define MAP

Maximum allowable pressure is calculated using measurements of remaining wall thickness and pit depths

5

Define PF

This is a calculated pressure at which a failure is predicted due to condition of the pipe and other factors pressure should never exceed this level

6

Define factor of safety

Variable used in the calculation of the PF an MAP that is based on factors such as population environment location and other safety concerns the more risk to life or environment the lower the MAP will be calculated

7

If MOP is higher then MAP

MAP takes precedence

8

If MAP is higher then MOP

MOP takes precedence

9

If PF is lower than the MOP or the MAP

PF takes precedence

10

Magnesium Zinc and aluminum; Most electronegative potential

Most anodic; most active; least cathodic; least Noble

11

Copper platinum carbon graphite; Most electropositive metal

Least Anodic; least active; most cathodic; most noble

12

The point at which water will not accumulate

Critical velocity

13

How many gallons in a barrel?

42 gallons

14

In KAPA when the wall thickness decreases the MAP

Decreases

15

How many quarts in a gallon

4 quarts in a gallon

16

How many pints in the quart

2 pints in a quart

17

How do you calculate parts per million

Divide by 1 million

19

Iron counts: When the iron count increased by five times the corrosion rate almost?

Quadrupled this is almost a directly proportional rate

20

Scaling tendencies: data shows that as the pH decreases; the scale index

Decreases

20

Scaling tendencies: data shows that as temperature decreases to 77° the scale index _________; but as the temperature decreases below 76°F the scale index______________

Increases; decreases

21

Iron counts: When the water production almost tripled the corrosion rate almost?

Tripled this reflects a directly proportional rate

23

Scaling tendencies: data shows that as the alkalinity decreases; the scale index__________

Decreases

24

Scale tendencies: Data shows that as the calcium decreases; the scale index _________

Decreases

25

Scaling tendencies: the data shows that as total dissolved solids (TDS) increases; The scale index_______

decreases
